BACKGROUND OF THE INVENTION

TNF-related apoptosis-inducing ligand (TRAIL; Apo2L) is an endogenous protein that selectively induces apoptosis in cancer cells. TRAIL is a powerful inducer of apoptosis in a wide range of human cancer cell lines via pro-apoptotic death receptor 4 (DR4; TRAIL-R1) and death receptor 5 (DR5; TRAIL-R2) at the cell surface through engagement of the extrinsic or intrinsic apoptotic pathways. TRAIL plays a direct role in tumor suppression during immune surveillance but this anti-tumor mechanism is lost during the disease progression. The ability of TRAIL to initiate apoptosis selectively in cancer cells has led to ongoing clinical trials with administration of recombinant TRAIL and the longer-lived TRAIL-agonist antibodies targeting either of its two pro-apoptotic death receptors.

Despite its potency, recombinant TRAIL has efficacy-limiting properties such as short serum half-life, stability, cost, and delivery. Delivery of recombinant TRAIL or TRAIL-agonist antibodies to the brain is limited by inability of recombinant TRAIL and TRAIL-agonist antibodies to cross the blood-brain barrier. Accordingly, there is a continuing need for anti-cancer compositions and methods.

In some embodiments, treatment of cancer comprises prevention of tumor growth in a cancer subject. In some embodiments, treatment of cancer comprises prevention of formation of cancer metastases in a cancer subject. In some embodiments, treatment of cancer comprises targeted treatment of minimal residual disease in a cancer subject known to have the minimal residual disease in a cancer or a subject at risk for having minimal residual disease.

This might be indicated after treatment of the primary tumor by surgery and/or after chemotherapy (e.g. radiotherapy) has been initiated or determined to efficacious. Disseminated tumor cells may be in their dormant state and often cannot be attacked by the chemotherapy (radiotherapy). A thus treated patient seemingly is in a healed state, which is also described as “minimal residual disease”. Nevertheless, the dormant tumor cells have a potential of forming metastases if they become metastasising cells due to a growth stimulus also after a longer dormant state.

As used herein, “minimal residual disease” denotes a small number of cancer cells that remain in a subject during treatment, or after treatment when the subject is in remission (exhibiting no symptoms or signs of the disease). The methods described herein are preferably applied to any form of the diseases listed herein, including adult and childhood forms of these diseases.

The solid was dried in the vacuum oven at 65° C. overnight (16 hours) to afford 200 g yellow solid.

To a 2 L three-neck round bottom flask equipped with mechanical stirring, N2 inlet, a thermocouple and a condenser, the above solid (200 g) was added, followed by ethanol (1000 mL). The mixture was heated to reflux at 78° C. for 2 hours. Upon cooling to room temperature, the solid was filtered through a sintered glass funnel and washed with ethanol (200 mL×3). The wet solid was dried in the vacuum oven at 85° C. for 3 days until the residual solvent met specification. 120 g of compound (2) was obtained as a white solid in a yield of 49%, with HPLC purity 99.7%.
